| | Abstract | | The estimation of S-wave velocity structure is essential to predict damage caused by earthquakes. We performed surface-wave tomography on the Metropolitan Seismic Observation network which is deployed around Kanto. Because of the thick sediment, higher mode Rayleigh waves are dominant in lower frequency and make it difficult to estimate dispersion curve of fundamental mode. To overcome this problem, we used Love wave for tomography because the higher mode Love wave are not dominant due to the thick sediments. Our results showed the low velocities related to distributions of the Shimosa and Kazusa group. Our velocity model can also contribute to disaster management and assessment. |
